JENNA JAMESON SHARES KETO DIET TIPS AFTER 80-POUND WEIGHT LOSS

“Now that I’m back from vacation, I definitely need to restart my #ketodiet,” she wrote on social media on Saturday.

“While on vacation I indulged, not in garbage but in whatever amount of good carbs I wanted. My scale reflected it less than I thought it would. I only gained 4 lbs. no worries! The best way to get back into #ketosis is to fast!” she added.

After an 18 hour-fast, Jameson returned to her pre-vacation weight.

“Within 2 days I was back at my pre vacation weight! So don’t stress if you fall off a bit, just buckle down after and keto on,” she said.
